SWITCHING CONTROL APPARATUS AND IMAGE FORMING APPARATUS

摘要

The switching control apparatus includes a switching driving unit for turning on and off the switch, a control-purpose power supply for outputting electric power, a power transmission unit provided between the switching driving unit and the control-purpose power supply, for supplying or cutting off electric power from the control-purpose power supply to the switching driving unit, and a control unit for controlling the power transmission unit. The control unit controls the switching driving unit to turn the switch on or off, during a period in which the electric power from the power supply to the switching driving unit is cut off by the power transmission unit, or supplied from the power supply to the switching driving unit.
